Ashyaakh (a Companion) from the tribe of Banu Salamah reported that `Amr ibn Al-Jamooh (another Companion) was a crippled man who suffered from severe disability. He had four sons, each of them was like a lion (i.e. very brave), and they used to participate in various battles with the Messenger of Allah, sallallaahu ‘alayhi wa sallam.
On the day of Uhud, they wanted to prevent him from going, and they said to him, “Allah has excused you from going.”
He went to the Messenger of Allah, sallallaahu ‘alayhi wa sallam, and said: “My sons are trying to prevent me from partaking on this battle and going out with you to participate in it. By Allah, I hope to enter Paradise despite my crippledness.”
The Messenger of Allah, sallallaahu ‘alayhi wa sallam, responded, saying: “As for you, Allah has excused you; there is no Jihaad obligatory on you.” Then he, sallallaahu ‘alayhi wa sallam, said to his sons: “Do not prevent him, perhaps Allah will bless him with martyrdom.” So `Amr ibn Al-Jamooh went out and fought, and was killed the day of Uhud.
Abu Qataadah (a Companion) said: “`Amr ibn Al-Jamooh went to the Messenger of Allah, sallallaahu ‘alayhi wa sallam, and said: ‘O Messenger of Allah, if I fight in Allah’s path until I am killed, would I walk in Paradise on this leg while it is healthy?” His leg was crippled. The Messenger of Allah, sallallaahu ‘alayhi wa sallam, responded: ‘Yes.’
He, his nephew, and a servant of theirs were killed on the day of Uhud. The Messenger of Allah, sallallaahu ‘alayhi wa sallam, passed by him and said: ‘It is as if I am looking at you walking in Paradise with your leg healthy.’
